.AVIATION...
Precipitation coverage so far today not quite as extensive as it
has been the last couple of days. This is likely due to the grow-
ing influence of the ridge over the Southern Plains. However that
being said, models are hinting at another round of SHRA/TSRAs for
tomorrow afternoon/evening with the approach/passage of a distur-
bance under this ridge from the east. PWs progged to climb to at/
around 2" with this feature. As such did keep with the mention of
VCSH starting early tomorrow morning at GLS...then working inland
through the day. Given the expected clear skies/light winds/lower
dewpoints, no arguments with the mention of very patchy fog over-
night. 41

.PREV DISCUSSION... /ISSUED / 1033 AM CDT WED JUL 20 2016

Minor changes have been made to the forecast based on model
trends and observations. Due to the large ridge axis sitting off
to the north, deeper moisture will remain south of I-10 today
increasing the chance for showers and thunderstorms to about 30%
for this region. High temperatures will remain consistent, hitting
the mid to upper 90s in the early evening. 08
